A malicious or malfunctioning Wi-Fi device can exploit improper validation of an EEPROM (Electrically Erasable Programmable Read-Only Memory) address during a copy operation. This can lead to an out-of-bounds write, which may result in memory corruption and potentially allow for arbitrary code execution.\n\n## Vendor advisories\n\n- **Red Hat VEX** · Moderate · updated 2026-09-14 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-80935.json)\n\n**kernel: wifi: mt76: mt7996: bound the device EEPROM address before the EFUSE copy** — rated Moderate by Red Hat.
